In the embodiment of Fig. I gratings 40, 42 are provided at either side of input and output interdigital transducers 21, 25 so as to constitute a band pass filter or oscillator frequency control element. The gratings are constituted by conductive or non-conductive strips or of etched grooves with a centre-to-centre distance of #/2. where # corresponds to the centre frequency of the resonator. The gratings 40, 42 are separated by approximately an integral number of half-wavelengths, and the areas of maximum surface wave excitation associated with the transducers preferably coincide with maxima of the standing wave pattern. Modifications are envisaged in which one or both transducers are positioned outside the region between the two gratings. Also a plurality of resonators as shown in Fig. 1 may be connected in series and/or parallel (Fig. 2, not shown) the individual frequency responses and couplings of the resonators being chosen to provide a desired overall frequency response; adjacent resonators may be isolated by absorbing material or grooves or by providing them on separate substrates. In an alternative modification (Fig. 3, not shown) an additional grating (43) is provided between the transducers so as to provide two resonating structures whose frequencies may be slightly staggered. A further modification (Fig. 5, not shown) comprises a single transducer between the gratings. The embodiment of Fig. 4 has an input section, comprising gratings 123,124 and transducer 125, coupled via multi-strip couplers 136, 137 to an output section comprising gratings 130, 131 and transducer 132.

Title: Sheet transfer mechanism for rotary printing presses
IPC: B41F21/10
Filed: 1959-06-03
Abstract: 869,983. Printing machines. MIEHLEGOSS-DEXTER Inc. June 3, 1959 [Aug. 21, 1958], No. 18952/59. Class 100(2) Mechanism for transferring sheets from an impression cylinder to another cylinder in a rotary printing press comprises a series of grippers mounted for rotation about a fixed axis in a circular path having a point of tangency with each of the cylinders, a concave shell member having a radius of curvature slightly greater than the radius of the gripper path, mounted adjacent to the gripper path and extending substantially between the points of tangency for guiding the sheet along the gripper path, and a transverse vane member mounted for movement with the rotating grippers and coacting with the shell member to create a differential of air pressure upon the two faces of the sheet whereby the body of the sheet is maintained in contact with the shell member while the sheet is advanced by the series of grippers. As shown a multi-colour press comprises two printing couples A, B. Printed sheets are fed from the impression cylinder 10 of printing couple A to the impression cylinder 13 of the printing couple B for a second impression by three rotary transfer members 20, 21, 22. The member 21 is a full-sized transfer drum round which the sheets are carried printed face outwards. The members 20, 22 are substantially identical and each comprises a drum 27, Fig. 4, from which radially extend brackets 26, 31. The brackets 26 support a gripper shaft 25 on which is mounted a series of gripper fingers 24 each co-operating with a pad 28 mounted on a bar 29 supported by the brackets 31. The drum 27 is journalled in the side plates of the machine by members 33 which are eccentrically disposed on the drum so as to counterbalance the gripper assembly. The transfer members 20, 21, 22 are rotated in timed relation with each other and with the impression cylinders. The grippers 24 are operated by a cam follower on the shaft 25 which engages a cam track secured to one of the side plates of the machine. A curved shell member 48, supported by bars 49, 50, is mounted adjacent to the gripper path and extends substantially from the point where the grippers 24 receive a sheet from grippers on the impression cylinder or the cylinder 21 to the point where the grippers 24 release the sheet. As the transfer members 20, 22 rotate the bar 29 on each functions in much the same way as the vane of a pump to remove a substantial amount of the air from adjacent to the inner surface of shell whereby the sheet held by the grippers 24 is maintained in contact with the shell until it is released by the grippers. To prevent the trailing edge of the sheet from falling away from the shell as the sheet is being transferred to the impression cylinder 13 blasts of air are directed against the inner face of the sheet from a perforated tube 57.

Filed: 1927-07-18
Abstract: 304,252. Boby, Ltd., R., and Robine, A. July 18, 1927. Heckling-machines; grip-chain and like arrangements for feeding, holding, and conveying fibrous materials.-In a machine of the kind in which the flax &c. is exposed to the action of pins carried by endless travelling sheets operating both sides of the stricks, the action of the pins on the material at all parts of the length of the stricks is varied by causing portions of the sheets to be protruded beyond their normal paths and to approach one another at the beginning of the cycle of operations. Two machines arranged tandem may be employed to complete the heckling of the whole length of the stricks. The stricks are gripped and carried through the machines by chains S, T, P, R, Fig. 3, of the kind described in Specification 245,511. The machine is driven from the shaft B, which is geared to the shaft C, the heckle sheets being driven from these shafts. The stricks are carried forward intermittently at a constant level and blank portions j<8>, k<8> are provided on the heckle sheets to permit the forward movement. Shafts D, E, Fig. 4, carrying tangential arms H provided with rollers to engage the inner surfaces of the heckle sheets are geared to the. shafts B, C and operated so that the arms H engage the sheets and cause them to protrude beyond their normal path at the beginning of the operative cycle. The upper carrier pulleys M, N for the sheets are mounted in inclined guides m<3>, n<3> and are controlled by springs m<4>, n<4> and cams f<1>, g<1> on shafts F, G geared to the shafts E, F. The. heckling commences between the arms H, the upper pulleys being drawn apart. The arms H then pass out of action and the pulleys M, N are caused to approach one another by the cams f<1>, g<1>. At the end of the cycle the pulleys M, N move apart again and the strick is free to move forward. The shaft F drives, by means of a chain f<3>, a cam f<6> which controls a bent weighting bar W, which comes into operation to increase the grip of the chains on the stricks during heckling. The shaft G carries a cam g<2> adapted to rock an arm g<3> and operate a ratchet g<6> through a pawl g<5>, and produced the intermittent movement of the pulley p<2> operating the chain P. The co-operating belt R is carried along by friction. The chains S, T of the otherpart of the machine are operated from the shaft g<9> of the pulley p<2>.

Title: Improvements in or relating to flock cutting
Inventor: SARGEANT ARTHUR HENRY
IPC: D01G1/02
Filed: 1964-05-08
Abstract: Flock having a coefficient of variation of length not greater than 50% is cut from uncrimped artificial filament tows by forwarding the tow, at least partially creased in a wrapping, along a shoot to a cutting means; the wrapping answers that all portions of the tow are forwarded to the cutting means at the same rate, the cut wrapping thereafter being removed from the flock. The wrapping may be of paper, preferably with a moisture resistant lining, e.g. polythene, which is caused to unroll under the tow as it enters the shoot, the paper being automatically folded and secured around the tow in the form of a tube.  The cut wrapping may be removed by spike means mounted near the cutting means or by cutting the flock on to an angled vibrating sieve, the flock passing through the sieve to a collecting means.  The flock made by this process may be projected electrostatically on to an adhesive coated backing material to form a pile fabric.
